Description

Technical Field

[0001] This utility model relates to the field of roller pressing technology, and in particular to a roller press surround-type scraper dust removal device. Background Technology

[0002] Roll forming is a process that uses the plastic movement characteristics of materials to form various complex parts by rolling extrusion. The roller press used consists of two rollers that rotate synchronously in opposite directions, one is a fixed roller and the other is a movable roller.

[0003] During the rolling process, a lot of dust and impurities from the rolled workpiece usually adhere to the surface of the roll. For example, during the rolling of electrode sheets, the coating material on the electrode sheets often adheres to the surface of the roll, affecting the rolling quality. Since these coating materials are insoluble in liquid, the general treatment method is to soften them by spraying water and then wipe the roll to remove these dust and impurities.

[0004] However, some very fine dust and impurities cannot be easily removed by wiping the rollers alone. A scraper is needed to scrape off the fine solids remaining on the rollers. When the existing scraper is used, the larger impurities scraped off fall freely, while the fine dust flies away from the rollers in an arc along the scraping direction, causing pollution to the production environment. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a roller press surround-type scraper dust removal device that effectively scrapes off the dust and impurities adhering to the surface of the roller and ensures a clean and tidy working environment.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a roller press surround-type scraper dust removal device, including side plates that are parallel to each other at the front and rear ends of the roller press. A scraper for scraping debris from the outer circumference of the upper roller of the roller press is rotatably arranged between the left ends of the side plates. A dust collection box for storing the debris and dust scraped off by the scraper is located below the scraper. The left end of the dust collection box has an inclined plate that is inclined to the upper left. A partition is provided inside the dust collection box. The partition includes a flat plate fixed in the middle of the dust collection box. The left end of the flat plate has a guide plate that is inclined in the same direction as the inclined plate. There is a discharge channel between the guide plate and the inclined plate for the debris and dust scraped off by the scraper to flow into the bottom of the dust collection box. The upper end of the guide plate has an arc plate that bends into the dust collection box. A dust suction pipe for discharging debris and dust is connected to the bottom of the dust collection box.

[0007] To enable the scraper to rotate to the scraping position, the inner side of the side plate is provided with a driving mechanism to drive the scraper to rotate and move closer to or away from the outer circumference of the upper pressure roller. The driving mechanism includes a cylinder and a fixed seat. The mounting end of the cylinder is movably connected to the inner side of the side plate through a pin. The inner ends of the front and rear sides of the scraper are movably connected to the inner sides of the corresponding side plates. The upper end of the fixed seat is fixed to the bottom surface of the outer end of the scraper, and the lower end of the fixed seat is movably connected to the piston rod of the cylinder. The left end of the side plate is rotatably provided with a limiting roller that presses against the upper surface of the scraper when the scraper rotates to the scraping position.

[0008] Specifically, the scraper includes a scraper, an upper clamping plate, and a lower clamping plate. The scraper is fixed between the upper clamping plate and the lower clamping plate. The upper end of the fixing seat is fixed to the bottom surface of the lower clamping plate. The inner ends of the front and rear sides of the lower clamping plate are movably connected to the inner sides of the corresponding side plates through a rotating shaft. The limiting roller presses against the upper surface of the lower clamping plate.

[0009] Furthermore, a limiting seat is fixed to the left end face of the side plate, and a limiting shaft facing the lower clamping plate is fixed inside the limiting seat. The limiting roller is rotatably mounted on the limiting shaft.

[0010] Furthermore, the bottom of the dust collection box has three conical hoppers arranged sequentially along the front-to-back direction of the dust collection box, and the suction pipe is connected to the bottom pipe of the conical hopper to discharge the debris and dust flowing down from the material discharge channel.

[0011] Furthermore, in order to balance the suction force among the three conical hoppers, the diameter of the suction pipe increases sequentially from the conical hopper at the rear end of the dust collection box to the conical hopper at the front end of the dust collection box.

[0012] Furthermore, the dust collection box is provided with support frames at the bottom of both the front and rear ends, and the support frames are fixed to the wall panels at the front and rear ends of the roller press.

[0013] To prevent dust from leaking out and affecting the working environment, a dust cover is fixed on the dust collection box, and the upper end of the dust cover has a dust cover plate that covers the scraper.

[0014] The beneficial effects of this utility model are as follows: By setting a material drop channel below the scraper in the dust collection box, larger impurities and dust scraped off by the scraper can fall directly from the material drop channel and be sucked away by the dust suction pipe, while finer dust can fall onto the flat plate of the partition for collection. In this way, impurities and dust on the outer surface of the roller can be effectively cleaned, ensuring a clean and tidy production environment. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] like Figures 1-3 The invention relates to a roller press enclosed scraper dust removal device. The roller press includes a frame, wall plates fixed on the front and rear sides of the frame, and two opposing and synchronously rotating rollers installed between the wall plates. The upper roller 15 is the driving roller, and the lower roller 16 is the driven roller. The rolled electrode sheet 17 enters from the left side of the roller between the upper roller 15 and the lower roller 16, and exits from the right side of the roller after rolling.

[0023] The scraper dust removal device is located on the right side of the upper roll 15 and the lower roll 16, and includes two side plates 1 fixed to the wall of the roller press. A scraper located on the side of the upper roll 15 is rotatably arranged between the two side plates 1. The scraper 2 includes a scraper 2-1, an upper clamping plate 2-2 and a lower clamping plate 2-3. The scraper 2-1 is fixed between the upper clamping plate 2-2 and the lower clamping plate 2-3. When scraping off impurities and dust, the tip of the scraper 2-1 is in contact with the outer circumferential surface of the upper roll 15.

[0024] Both inner sides of the two side plates 1 are equipped with a drive mechanism that synchronously drives the scraper 2 to rotate to approach or move away from the outer circumference of the upper pressure roller 15. The drive mechanism includes a cylinder 5 and a fixed seat 6. The mounting end of the cylinder 5 is movably connected to the inner side of the right end of the side plate 1 via a pin. The right ends of the front and rear sides of the lower clamping plate 2-3 are movably connected to the inner side of the corresponding side plate 1 via a rotating shaft. The upper end of the fixed seat 6 is fixed to the bottom surface of the left end of the lower clamping plate 2-3, and the lower end of the fixed seat 6 is movably connected to the piston rod of the cylinder 5.

[0025] A limiting seat 8 is fixed to the left end face of the side plate 1. A limiting shaft facing the lower clamping plate 2-3 is fixed inside the limiting seat 8. A limiting roller 7 is rotatably mounted on the limiting shaft. When the scraper 2 rotates to the scraping position, the limiting roller 7 presses against the upper end face of the lower clamping plate 2-3, cooperating with the fixing seat 6 to limit the position of the scraper 2 relative to the upper roller 15, thus ensuring the scraping effect. Figure 3 This is a schematic diagram of the drive mechanism after the dust cover 13 has been removed.

[0026] A dust collection box 3 is provided below the tip of the scraper 2 to store the debris and dust scraped off by the scraper 2. Support frames 12 are provided at the bottom of the front and rear ends of the dust collection box 3, and the support frames 12 are fixed to the wall panels on the front and rear sides of the roller press.

[0027] The dust collection box 3 has an inclined plate 3-1 at its left end that slopes upward to the left. The tip of the scraper 2 protrudes slightly beyond the top of the inclined plate 3-1. The dust collection box 3 is equipped with a partition 9. The partition 9 includes a flat plate 9-1 fixed in the middle of the dust collection box 3. The left end of the flat plate 9-1 has a guide plate 9-2 that slopes in the same direction as the inclined plate 3-1. The guide plate 9-2 and the inclined plate 3-1 form a material discharge channel 10 that allows the debris and dust scraped off by the scraper 2 to flow into the bottom of the dust collection box 3. The upper end of the guide plate 9-2 has an arc plate 9-3 that bends inward into the dust collection box 3. Through the action of the arc plate 9-3, the opening of the material discharge channel 10 can be enlarged accordingly, making it easier for larger dust and impurities scraped off by the scraper 2 to fall into the dust collection box 3.

[0028] The dust collection box 3 has three conical hoppers 11 arranged sequentially along the front and back direction of the dust collection box 3. The bottom of the dust collection box 3 is connected to a dust suction pipe 4 for discharging debris and dust. The dust suction pipe 4 is connected to the bottom pipe of the conical hopper 11 to discharge debris and dust flowing down from the material discharge channel 10.

[0029] To balance the suction force of the suction pipe 4 among the three conical hoppers 11, the diameter of the suction pipe 4 increases sequentially from the conical hopper 1 at the rear end of the dust collection box 3 to the conical hopper 11 at the front end of the dust collection box 3.

[0030] A dust cover 13 is fixed on the dust collection box 3, and the upper end of the dust cover 13 has a dust cover plate 14 that covers the scraper 2.

[0031] See Figure 4As shown, taking the rolled electrode sheet 17 as an example, the electrode sheet 17 passes between the upper roller 15 and the lower roller 16 of the rolling mill for rolling. In the initial state, the scraper 2 is tilted to the lower left. The cylinder 5 is activated, pushing the scraper 2 to rotate around the rotating shaft and lift it up until the tip of the scraper 2-1 is in contact with the outer circumferential surface of the upper roller 15. At this time, the limiting roller 7 is pressed against the upper end surface of the lower clamping plate 2-3. The cylinder 5 stops, keeping the scraper 2 in the same position. As the upper roller 15 rotates, the scraper 2-1 can scrape off the impurities that remain on the outer circumferential surface of the upper roller 15. The relatively large impurities fall from the opening of the material discharge channel 10 into the dust collection box 3 and are sucked away by the suction pipe 4 under negative pressure. Some of the fine dust will fall into the flat plate 9-1 in the middle of the dust collection box 3 and be collected.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
